i went into a valvoline with my legacy he tried to upsell me a tranny flush due to my mileage he was very adamant showed me diagrams and everything it took a little bit to explain to him that the transmission he showed me in the diagram isnt whats in my car and that his computer is wrong and that my car doesnt need tranny flushes i kinda felt like an ass but i figure maybe some bit of education is better than just saying no thanks
